This invention relates to a kcorn `planter or similar'agriculturalimplement, and particularly :to a corn planter of, the `twowheel'edJ-type. As is well known'to those :skilledin the art, such corn planters are/now Ymade with -arigid frame supported'on two axially alined wheels,y which frame carries "the-f grain lholding receptacles and lin ,the standard:construction, has a tongue rigidly secured thereto and. projecting 'forwardly therefrom at each sideof which the -horses are hitched. With vsuch a Construction the vibration of the frame 'caused bythe-un- Yevenness `of* .the lgroundV is transmitted t0 thetongue an'd the tongue therefore :jerks against the horses, and harness.' The horses falways iiiove somewhatfyrom 'side tofside and in so doing A'they transmit the lateral `motion to the tongue which is iny turn transmitted to the frame which is thus unnecessarily moved from-side to side. 'It is'not necessary for ,proper steering of the corn planter that the tongue be rigidly connectedto the frame.

lt is an object of this invention, therefore, to :provide a two-wheeled corn planter or similar implement having a rigid frame and va supporting member 'atthe frontend thereof movable'about a vertical axis and 4having a supporting wheel at its lower. end, the tongue Vbeing horizontally pivoted in said member; I n

I't A-is a further object of the 4invention to provide Aa ytwo-wheeled corn 4planter having 'a rigid frame 'with a-membergprojecting forwardly and centrally therefrom, together with Ameans extending through said member and .journaledtherein about Ia 'vertical axis, halvifng a flanged supporting wheel at its lower end and to which the tongue is `pivotally 'connected about a horizontal axis.

It is stiljl another object of the invention "to provide ay two-wheeled corn planter -havingla rigidframe with a i'ne'riiber,pr "Qecting forwardly and'cent-rally therefrom,

together with a rod extending through tsaid member andv journaled therein labout aI ver,- tical "axis, which r'od extends downwardly from said member and is bent into hori- 4Zon-tai position at its lowerend 'toform ythe axle of supporting wheel having a comparatively wide tread and a flange at the center thereof, said rodV having aI coupling clampedthneretoabove said member to which theftongue is pivotally connected about a horizontal axis, said member also prefer- -ne,cted .thereto at itssforward end.

collar 13 thereon extending between the bars 8.v Above the upper member 8 rod 10 has a coupling member 14 secured thereto,

Vwhich member' is inthe form of a splitV sleeve having rearwardly projecting flanges connected by the headed and nutted boltsV 15. The member 14 is thus .clamped securely to the upper end of rod 10. Member 14 has pivoted .thereto abouta horizontal axisthe `bracket'l having right angled flanges ex- Vvtending along Vthe rear end and bottom respectively of the tongue member 17 to which Vit is connected by the headed and nutted bolts 18 extending through the lower flange of said tongue as well as by the screw 19 extending through the rear flange. The plates 8 extend forward of the rod 10, the upper plate being offsetV downwardly to extend closer to the lower plate and a double tree is disposed between said pla-tes and pivotally connected thereto by the pin 21.

With the described construction, the horses will be hitched at each side of the tongue 17 and connected to the doub-le tree 2O in theV usual manner. The planter will be drawn by the tongue 17 acting through the rod 10. and will be partially supported by the wheel v11. The planter will be steered as usual by the horses moving to one side or the other, this movement being transmitted to rod 10 which in turn turns the Vwheel 11. Any lateral vibration, however, of the frame 3 Yof' the planter will not be transmitted to the tongue 7 as the frame can pivot about the rod 10. Any vertical vibration of the planter. will also not be transmitted to the tongue 10 as the frame can. swing about the pivotedy connecting members 14 and 16. The tongue can also be moved up and down by the vmovement of the horses without each time tilting the frame 3 as the tongue willzpivot about the pivotal connection to the member 14. At the same time, the front end of the planter is effectively supported by the wheel 11 and a large amount of the weight thus taken from the tongue and horses. The flange 11b yon the -wheel 11 results in the planter holding The rod 10 may also have a to its course vwhen the main wheels of the same strike a stone or drop into a hole or rut. Vithout the flange, the wheels and planter circumstances tend to skew. L,The flange 11b Vsinks down into'the soil or ground '22 as shown in Fig. 2,v and prevents this skewing of the planter and the operation of the planter is thusrmade much more steady and uniform and the same is pulled with greater ease by the horses. A very flexible and convenient implement is thus provided.

From the above description it will be seen that applicant has provided a very lsimple and e'liicient structure .of supporting and traction means for a two-wheeled corn planer or a` similar implement.` The invention can be readily and easily installed onall standard forms of corn planters andV this can be very yeasily done with comparatively small expense.l The devicev has been amply demonstrated in actual practice and found to be very successful and efficient. It w1ll, of course, vbe understood that variwould under suchV ous changes may be made in the form, de-

tails, arrangement and proportions of the parts, without departing from the scope of applicants invention, wl1icl1,generally stated, consists in a device capable of carrying out the `objects above set forth, in the novel parts and combinations of parts disclosed and defined in the appended claims.

lVliat is claimed isr- 1. 4The combination with a corn planter having a rigid frame supported on two axially alined wheels and having a member projecting forwardly and centrally therefrom, a rod journaled insaid member about a vertical axis and extending downwardly therefrom, said rod being bent horizontally at its lower end -to form an axle, a flanged wheel journaled on said axle adapted to support said frame, ra coupling member secured to said rod above vsaid first mentioned member and a tongue member pivotally connected to said coupling member to swing about a horizontal axisand means for adjusting the height of said coupling member on said rod.

2. The combination with a farmr imple-V ment having a rigid frame supported on wheels and a member extending forwardly from said frame, of means pivotally connected to the front portionof said member and swingable about a vertical axis therein, a supporting wheel carried kby said means, a tongue, and means vertically adjustable on said first mentioned means for pivotallysecuring said tongue to said first mentioned means. for swinging movement about a horizontal axis. f
